Institutional Grade Research Peptides.Quality You Can Verify.
Third-party tested research peptides, shipped from the U.S. Every order ships with an HPLC purity report, mass spec identity check, and a Certificate of Analysis.
HPLC Purity ≥ 99%
Every production lot is run through high-performance liquid chromatography before release. The purity figure on the label is a measured result — not a marketing claim.
Mass-Spec Identity
Molecular identity is confirmed by independent mass spectrometry, so the sequence inside the vial is the sequence on the label.
Per-Batch COA on the SKU
A third-party Certificate of Analysis is attached to the exact lot you receive — purity, identity, lot number, and the analytical methods used to verify it.
